I like how easy it is to use, as well that's super fast when you need help with something specific or just want some advice from someone else in your team (which happens often).
The only downside of this app so far has been its price tag - which isn't cheap at all but worth every penny if used correctly! It saves me time by having access 24/7 via my phone without needing an internet connection; there are times where we're not able get online for whatever reason & being connected through slack makes life easier than trying to find another way around things such us emailing other people directly etc.,.
